Composting Toilets

Nature's way of dealing with waste, or actually declaring there is no such thing...

Sun-Mar Corp. has been a world leader in composting toilets for over 25 years. Sun-Mar units are simple to operate because composting is accomplished in an easy to manage drum and because evaporation and compost removal are semi-automatic. A Sun-Mar can be used anywhere, any time, and is the favorite composting toilet of our customers.  We recommend the Excel model.

For large volume uses consider the Phoenix Composting systems. Our friend Tad Montgomery can get them for us and they are a superior composting toilet system.

Phoenix Residential Models
Phoenix residential packages contain all of the components necessary for an installation except for the wood shavings starter bed for the tank, and the 4-inch (100 mm) rigid vent pipe. Every package includes a Phoenix tank, one toilet with three feet (910 mm) of chute, a complete ventilation system, a manual liquid spray system, a compost bin, rake, and installation and operating instructions.
Capacity. The capacity of the Phoenix system depends on the size of the tank, the temperature of the compost pile, and the frequency and quality of maintenance. Warm tanks have a higher capacity than cold tanks. Our capacity ratings assume a minimum tank room temperature of 65F (18 C), our minimum recommended temperature. Below 55F (13 C), composting is very slow.
The R-199 “cabin model” can be used continuously by two persons.
The R-200 accommodates four full-time users.
The R-201 accommodates eight full-time users.
Model R-200 can be upgraded by adding a midsection. Model R-199 can be upgraded by adding a midsection and/or a 200 level top.

Advantages of the Phoenix
Odorless. There are no unpleasant smells in the toilet room, tank area, or around the building. Aerobic decomposition and a ventilation fan ensure odorless operation. Finished material is inoffensive.
Waterless. Designed for dry operations. No flushing saves thousands of gallons of water per person.
Rugged. Lasts a lifetime! Thick, tough, insulated crosslinked polyethylene walls, and corrosion resistant fittings.
Capacious. Accommodates families, guests, relatives. Large surge capacity.
Owner-friendly. Easy maintenance is a hallmark of the Phoenix's field proven design. Finished compost is removed just once a year.
Frost-safe. Freezing does not injure the composting process. Use of the Phoenix in cold weather can continue at a lower rate. Composting resumes when the system warms up.
Energy efficient. A 5-watt fan is the only electrical load in residential units.
Chemical-free. Requires only an organic bulking agent such as wood shavings. No Chemicals! Composting uses a wide variety of organisms to decompose wastes naturally.
Clog-proof. Rubber balls, apples, and other items that stop up conventional flush toilets won’t clog the foot-wide chutes connecting the toilet and food waste inlet to the Phoenix composting tank.
Pollution-free. Wastes are totally contained in the Phoenix. No cracks, no leaks. A long, uniform, retention time ensures a stable, biologically benign end product, reduced 80 to 90 percent in volume, that can be easily transported or disposed of on-site.
